The rock spllite is a type of portable hydraulic tool that is used in demolition jobs which involve breaking large blocks of concrete and rocks. Its use in geology was first popularized by volcanologist David Richardson.

Advantages

Directivity:Hydraulic methods means controlled methods, cylinder handle direction will be the splitting direction, special if user carve  a groove on the material, it will get a better effect.
Safe:As a alternative technology compare to blasting, impact breaking, hydraulic method is vibration free, impact free, it means more safe then traditional methods.
Economical:Hydraulic cylinder only need a very low fuel flow to drive the piston work, according to calculate, more economical then sawing, drilling.
High efficiency: Only few seconds the rock splitter can split big stone into parts, and the cracks are deep and width if you tried a reasonable settlement and splitting cylinders.
Easy Operation: Easy to learn and use, only one people can operation.
